Given numbers are 855, 625, 666, 225

The list of prime factors of all numbers are

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 625 are 5 x 5 x 5 x 5

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 225 are 3 x 3 x 5 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 855, 625, 666, 225

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(855, 625) = 106875

GCD(855, 625) = ( 855 x 625 ) / 106875

= 855 / 625

= 855

Step2:

LCM(5, 666) = 3330

GCD(5, 666) = ( 5 x 666 ) / 3330

= 5 / 666

= 5

Step3:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1

So, Greatest Common Divisor of 855, 625, 666, 225 is 1
